Recently we got chance to interview Monster Hunter Tri's producer Mr Ryozo Tsujimoto and had to ask him about the continent-specific servers that prevent monster hunters from opposite sides of the Atlantic from playing with each other. Although there was initially hope that the region lock-out would be a temporary measure, Mr Tsujimoto confirmed our worst fears by saying it's around to stay.
Due to several affecting factors I’m afraid we need to keep the servers separated.
Mr Tsujimoto didn't expand upon these factors but we have contacted Nintendo for a follow-up. The rest of the interview containing many other interesting nuggets will be available later tonight, so it's not all bad news.
